Embodiment G-1

[0164] Add 15kg of triethyl orthoformate, 20kg of diethanolamine, and 10kg of water into the reactor, start stirring, control the pressure not higher than 0.1MPa, slowly raise the temperature under constant stirring, when the temperature rises to 80°C Temperature controlled reaction for 10 hours. After the reaction is completed, cool down to 50°C, then control the vacuum to be below 600 mmHg, remove ethanol under reduced pressure at a temperature below 50°C, and release the product after cooling down to below 40°C to obtain compound G-1 with a viscosity of about 500 centipoise , pH=8.0, decomposition temperature at 45-70°C.

Embodiment G-2

[0166] Add 15kg of trimethyl orthoformate, 2.0kg of ethylene glycol, 10kg of water, and 6.0kg of ethylenediamine into the reactor, start stirring, control the pressure not higher than 0.1MPa, and slowly raise the temperature under constant stirring , when the temperature was raised to 70°C, the temperature was controlled for 5 hours. After the reaction is completed, lower the temperature, then control the vacuum to be below 600 mm Hg, demethanol under reduced pressure at a temperature below 50°C, remove the vacuum, and release the product after cooling down to below 40°C to obtain compound G-2, with a viscosity of about 250 centipoise , pH=8.3, decomposition temperature 45-70°C.

Embodiment G-3

[0168] Add 15kg of triethyl orthoformate, 13kg of monoethanolamine, and 7.0kg of water into the reactor, start stirring, slowly raise the temperature under constant stirring, and control the temperature below 100°C for 8 hours. After the reaction is completed, lower the temperature, then control the vacuum to be below 600 mm Hg, remove ethanol under reduced pressure at a temperature below 50°C, remove the vacuum, and release the product after cooling down to below 50°C to obtain two esters of triethyl orthoformate The compound G-3 which undergoes hydrolysis. The viscosity is about 300 centipoise, pH=8.1, and the decomposition temperature is 45-70°C.

Abstract

The invention discloses an orthoformic acid organic amine salt compound A<n->[B<m+>]p with the following general formula (I). In the formula (I), A<n-> is an orthoformic radical, B<m+> is or includes an ammonium ion and / or an organic amine B positive ion, m is 1-10, p is larger than 0 and smaller than or equal to n / m. The compound with the general formula (I) has at least one hydroxyalkyl group connected with an N atom, that is, the compound has alcohol amine residue. The compound can be used as a polyurethane foaming agent or a polystyrene foaming agent or a polyvinyl chloride foaming agent.

Description

technical field [0001] The present invention relates to having as CO 2 Anionic organoammonium compounds of the donor and their use as blowing agents, more specifically, providing not only 2 The anion of the donor and has a hydroxyalkyl or hydroxyalkylalkoxy group as a solubilizing group or a C2-C14 hydrocarbon group (such as 2-chloroethyl, 3-chloropropyl or phenethyl) as a solubilizing group A new type of organic ammonium salt compound, and its application in foam materials such as polyurethane foam or PVC foam or polystyrene foam. technical background [0002] As a new polymer material, polyurethane rigid foam is light in weight, high in strength and has extremely low thermal conductivity. Automobiles, refrigerators and freezers and other household appliances and other industries. The most important raw material in the production of rigid polyurethane foam is the blowing agent. At present, these blowing agents are chlorofluorocarbons except cyclopentane. Because of thei...
